WALL-FLASHING.

Application filed. October 1,

To aZZ 1127mm it may concern:

Be it known that I, WILLIAM L. l-lAwLnY, a citizen of the United States,and a resi dent of the city of North Little Rock, in the county ofPulaski and State of Arkansas, have invented anew and Improved lValLFlashing, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in wall flashings, an object ofthe invention being to provide a construction of wall flashing whichwill prevent possibility of leaking at the joint covered by theflashing.

A further object is to provide a wall flashing especially designed forreinforced con crete building structures and which can be anchored inthe wall as the latter is built and which will be comparatively cheap toinstall and most efficient in the performance of its functions.

lVith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings:

Figure 1 is a view in section showing a wall in course of construction.

Fig. 2 is a view in section on the line 2-2 of Fig. 1 showing theflashing complete.

Fig. 3 is an enlarged view in vertical section illustrating theflashing. 1

Fig. 4 is a fragmentary perspective view of the flashing strip.

1 represents a fragment of roof and 2 a wall joining the same both ofreinforced concrete.

As the wall 2 is molded between forms 3, a waterproof metal flashingstrip 4 is embedded therein. This strip is provided with bolts 5, havinganchoring ends 6 embedded in the concrete and every third bolt, or anynumber of said bolts are sufficiently long to project through the form 3and are secured by nuts 7 to securely hold the flashing strip whileforming the wall. These long bolts are cut off when the form is removed.

The bolts 5 are projected through spring metal strips 8 which are bowedtransversely and adapted to securely clamp any number of sheets ofwaterproof material 9 which extend across the joint 10 of the wall andceiling.

Specification of Letters Patent.

1919. Serial No. 327,628.

The flashing strip is of the shape shown in cross section in Figs. 1, 2and 4t, and is bent on a lon itudinal line at a sharp angle as shown at11 forming a lip 12 which extends to the edge of the wall and positionsthe main portion of the strip at an angle, to provide a recess in thewall.

The lower edge of the strip is bent at an angle and corrugated orotherwise shaped as shown at 13 to form a secure anchorage in the wall.

The sheets 9 are positioned between the strip i and spring strip 8 withtheir edges in the angle 11 and when the nuts 7 are screwed down theywill be securely held.

The roofing may of course be finished in any desired manner.

The metal strips l and 8 are preferably of steel suitably treated tomake them rust proof but I of course do not limit myself to anyparticular material.

The bolts 5 have their inner ends bent at an angle to form the anchoringends 6 embedded in the concrete and they may of course be otherwiseshaped if desired.

Various slight changes might be made in the general form of the partsdescribed without departing from my invention, and hence I do not limitmyself to the precise details set forth but consider myself at libertyto make such slight changes and alterations as fairly fall within thespirit and scope of the appended claims.

I claim:

1. The combination with a vertical wall, and a roof, of a flashing stripcomprising a plate inclined vertically with its lower edge flushwith theface of the wall and having an integral anchoring strip at its loweredge and an integral flange at its upper edge projecting to the surfaceof the wall, waterproof sheets located against the plate and extendingupwardly against said last-mentioned strip, and a spring clamping striphaving its edges located against the water proof sheets, bolts projectedthrough the flashing strip and through said clamping strip, and nuts onthe bolts for clamping said waterproof sheets against the flashingstrip.

2. The combination with a vertical wall, and a roof, of a flashing stripembedded in the vertical wall, said flashing strip comprising a plateinclined vertically with its lower edge flush with the face of the wall,said plate having an integral flange at its upper edge projecting to thesurface of the Wall and having an integral anchoring strip at its loweredge embedded in the wall, Water- 5 proof sheets located against theplate, a

spring clamping strip having its edges located against the Waterproofsheets, bolts anchored in the Wall and projecting through the plate ofthe flashing strip, through the Waterproof sheets and the clampingstrip, 10 and nuts on the outer ends of the bolts against the clampingstrip.
